Developed by the founder personally
The XACT brand was born out of my passion project. I developed every single product for my own use and later made it available for purchase. XACT embodies the knowledge, insights, discoveries, and experience I gained from my audio journey and as the creator of audiophile JPLAY software and innovative high-end audio hardware JCAT. It is absolutely the best I have to offer.

Philosophy:
Passion first,
business second
All XACT devices and accessories were developed to satisfy my own audiophile needs and improve my system. I introduced them later as commercial products available for purchase.
Research and experiment
without prejudice
During my explorations, I remain open-minded to all possibilities, even those that may seem unconventional or are universally disregarded by others. The ultimate priority is sound.
Ear-test with every change
No matter how small, each software and hardware modification undergoes meticulously logged, thorough ear-testing. Nothing is left to chance.
No compromises
XACT products are packed with the
best technology and components
available. No ready-to-use solutions
implemented, no shortcuts taken.
Reviews:
XACT S1 music server does not sound like a combination of countless quark-like aural particles, but rather like a well-designed, refined digital playback that delights the listener with a captivating fusion of software and hardware. The result is more than the sum of its parts. S1 looks, feels, sounds, and plays the part.

chief editor, Mono & Stereo
Its sound is extremely difficult to distinguish it from an analog recording.
A refined, well-thought-out, sophisticated product.

chief editor, HighFidelity
XACT S1 delivers signal translated by Pacific 2 (and other DACs) into astoundingly analog, or non-digital, non-fatiguing, natural sound.

XACT S1 music server tends to break the rules. To say the S1 is unlike other digital components is an understatement.
Marshall Nack
Positive Feedback
Maybe its crazy talk to say it, but the S1 with the right DAC gives me more of those qualities than vinyl right now so in my instance I think its fair to say the XACT S1 sounds more analogue than analogue which is very high praise.

Through the S1 EVO I could hear absolutely everything and was sucked into the sound… more than any previous listening session of this same music !
